Monitoring of Radioactive Emission from NPP in Real Time G.A. Kolotkov, S.T. Penin IAO SB RAS

IDEA Emission Nuclear Power Plant Gaseous Radioactive Emission (Isotopes of Ar, Kr, Xe, I) Radioactive Decay High-energy Beta-Electrons Photochemical Reactions H, OH radiate at the frequencies 1420 MHz and 1665-1667 MHz

Types of radiometer system Ground based radiometer Airborne radiometer Conclusion

Conclusion Frequencies, Power Doppler In spectral Attenuation Table of MHz radiated spectral range 1÷10 by the bandwidth from broadening GHz noise atmospheric assignment among volume background absorption radio services of emission of Russian 1 km ³ Federation 1420 10 -13 W 150 kHz less than less than 2dB allocated for radioastronomical 10 -21 W · m -2 (passive) research. Using 1665-1667 2 × 10 -11 W 31.5 kHz radiating radioelectronic devices in the specified bands is not recommended. • Radiant intensity on frequencies 1420 MHz and 1667 MHz has enough for monitoring of activity level of the nuclear power plant emissions from distance in 10s kilometers in real time. • As OH and Н radiate in one spectral range the perspective radiometer for radiation recording on frequency 1420 MHz can be used, without the considerable alterations and for radiation recording on frequency 1667 MHz.
